If you think you can do it, you can.

It's always too early to quit.

The wise does at once what the fool does at last.

Always desire to learn something useful.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

Leap, and the net will appear.
